GH MaxiGro

[LexLuthor]

Wud up Farmers, I just bought some MaxiGro and I just wanna know people's opinions. I use to use Fox Farm Grow Big 6-4-4, NPK ratio is basically 2-1.5-1.5, which IMO is an NPK ratio I don't like. Maxi is 10-5-14 so the ratio is 2-1-2.4 which I think is alot better. Now thats not the elemental ratio, but its still a good way to compare fertilizers. I also have GH Liquid KoolBloom which is 0-10-10 so I was thinking about using MaxiGro from seedling to harvest while adjusting the amount per gallon based on the stage of growth and also adding KoolBloom as a PK boost when needed. Has anyone ever done this or something similar?? I would also appreciate anyones advice and/or opinion on this nutrient regime on whether it would work good or not, thanks for any responses in advance.


P.S. I grow in soil and 100% perlite hempy's under a 600w HPS.

I use Maxigro as my low ppm flush and use it to give a bit more nitrogen to any plants that need more N then the CNS17 can give. I hardly ever PH and just follow my PPM. I grow in coco.

 

[LexLuthor]

Sounds like you got a good nutrient schedule. Do you think Maxi will do good as a 1-part veg+bloom formula with the addition of a PK boost (when needed) during the bloom phase??

 

[jkbeing]

I bought the maxigrow to add a bit over the tops of new plants that were heavier feeders then my normal strains and it worked great. If i was going to use just the maxigrow, I would go light on my feedings, especially in the soil. I didn't use any Pk boosts this last grow (I bought an A/C=had no $!) and my plants finished awesome with just CNS17 ripe.

 

[stutter]

most people tend to just use the maxi bloom start to finish. its basically just the lucas formula. can't say i have tried it though

 

[LexLuthor]

I know about the maxibloom lucas formula from start to finish, but I don't like the NPK ratio because there is way too much P compared to N for veg. That is why I am going to use the Gro and then use the PK boost. I have a couple questions for anybody that wants to answer it or put there 2 cents in. I'm using only the MaxiGro and KoolBloom in combination to come up with these ratios. Also, I'm in soil and sometimes perlite hempy's drain to waste.

What elemental ratio would be best for veg? 2.7-1-4 2-1-3.5 1.5-1-3

Now for bloom? ^^^All 3 above and 1-2.5-3.7 1-2.5-4.5

I can give the elemental ppm for those ratios if its more helpful for anybody. Thanks if anyone can give me there opinions.

Ive done this exact same thing before, didnt get quite the yield I got from using just straight Floranova bloom s.t.f. Plants started getting sign of over fertilization after about week 4 to 5. Knocked down my ppms and got yellowing before my flush. It works but its not ideal.

 

[LexLuthor]

I also forgot to mention that MaxiGro by itself for veg would be 4.5-1-5 elemental ratio. The other ratios were Gro and KoolBloom combinations.

@Dirty White Boy- Did you use MaxiGro and KoolBloom in combination during the entire grow or just during the bloom phase?? Also, how many tsp. or ml per gallon did you use of each?? Thanks in advance.

 

[Dirty White Boy]

1 tsp of maxigrow per gallon start too finish and I added liquid koolbloom one-two tsp per gallon at flip. I fiddled with this for a few cycles then gave up and went back to floranova bloom. I have tried maxibloom start to finish as well and that was killer.

There is no reason to use MaxiGro at all- MaxiBloom is a complete 1 part fert. You can use it in veg and bloom, and you
can add Koolbloom later in flower for some extra push. Use Protekt silica for PH up and that's it. It is easier and cheaper that most of the fert recipes out there and accomplishes the same thing.

@zombywolf- I don't understand how a ratio of 1-3-3 would be better then 2-1-3 during veg. Having 3 times more P then N doesn't make sense to me when plants are in veg. I'm not saying your wrong because I know there are people who use it successfully, but it just doesn't make sense on paper.

@Dirty White Boy- Thanks for the info because it helped alot. One more question, I know the Bloom was better then Gro during flower, but was it also better during veg?? The reason I ask is because of the reasons I stated above, 1-3-3 just seems like an inferior ratio for veg compared to 2-1-3.

Thanks everyone for your comments and opinions.

Lex,

It could be that the ratio isnt important in veg when it relates to N, and once you hit a minimum N number-more isnt
better. There have been numerous grows with Maxibloom in veg with 1/2 the N ratio and no signs of N deficiency (mine included). Same with an excess of P in Maxibloom-no negative effect in veg. The objective of using MB is effective fertilization in veg and flower with the same fert and measure- cant be said by many ferts out there. I think ferts are
overblown to begin with-give a plant the minimums they need and growth will be what the genetics deliver. MB is just
a very inexpensive and simple way to provide what our plants need- it can be made more complicated but not necessarily more better.

ive been playing with maxibloom and maxigrow for about a year. maxigrow is a pretty similar ratio to all the low P 2 part nutrients like h&g and h16. i have never ran it from start to finish but it should definately be perfect with a pk boost.

maxibloom is way too much P for veg and and the first 4 weeks of flower. running it from flip it took forever for my buds to get going. i switch to maxibloom around week 5 and it ripens up hard and flavorful. and no boosters with maxibloom, it will burn. ive ran it here and there in veg when i thought i needed a pk spike, but not regularly.

@zombywolf- MB is very simple and easy to use, but I don't think giving your plants a better veg solution in relation to NPK ratio is complicated and I'm trying to keep it simple by using only MG and KB. I guess it also depends on the medium and strain, I might use MB for flower but I already like what MG is doing to my plants in veg right now and its working great.

@justsomeguy- Thats what I think just by doing some math on paper, it should be perfect with a PK boost. I've talked to Capulator a lil about it and I'm basically gonna copy his flower formula with MaxiGro and KoolBloom so I'm confident it should work good. I'm gonna have to use about 3 ml/gallon of MG then about 5 ml/G KB, but I can tweak the formula whenever needed.

@Lex- Have you used the Jack's? Seems much cheaper then the MB.

Lex,

Going back to your original question- Is Maxigro the best option to use throughout the grow cycle? As I stated before, not
Maxigrow- Maxibloom will accomplish that goal. The tried and tested levels for fert is N100, P100, K200 and Mg60. Maxibloom at 7g/gal works out to be N92, P121, K215, Mg65. Maxigro at 7g/gal is N184, P40, K215, Mg36. The question you posed wasnt using MaxiGro for veg and maybe MB for flower, but one fert for all. It is quite evident that MG for veg will have the positive effects you are seeing, except for low Mg. Try it in flower and you will have major problems with all that N and low Mg. Since the K numbers are the same, we need only deal with N, P, and Mg between the two. N in MB is only slightly low from the optimal 100- closer to the optimal than the wild swing you would get from MG in veg and bloom. P value from MB is 20% more than optimum, MG is 60% low- you may argue the low P is better line, but the tested optimum is still 100. Mg is way off in MG, almost 50% lower than MB. MG has multiple major issues vs the Mel Frank standard 100/100/200/60 vs only a very small difference with MB. Hope this helps you with your evaluation of MG vs MB as a stand alone fert for veg and bloom.

 

[LexLuthor]

Hey zombywolf, my question was not about using one fert for all, it was about using MaxiGro and Kool Bloom in combination. My goal is not to use MG from seed to harvest, I already know MB would be better for that, but MG in combination with KB will give me the flexibility I want while also keeping it simple. I'm also not worried about Mg because the Mg in my tap water plus MG is sufficient for my plants. Now I'm not sure if Mel Frank's 100-100-200 ppm was for veg or bloom, but IMO in veg 100 ppm P is a too much and 100 ppm N is slightly too little. Now in flower I think 100-100-200 would be pretty good, but I can get very close to those numbers using only MG and KB. The point is if I use MG + KB instead of just MB I'll be able to give my plants a better veg formula and I can give them a great flower formula by adding KB. So I can tweak my formula by adding/subtracting KB and MG, but if I use only MB I won't be able to change the NPK ratio. I need to be able to change my NPK ratio from veg to flower which is why I don't wanna use MB as a 1-part fert.

Thanks for your response and opinion and I appreciate everyones help.

I mean I understand what your saying, but it dosnt work right.....not sure what else too say. Maybe youll be able to dial it in. But from experience it didnt work anywhere close too just Floranova or Maxibloom on its own. Problem is when you drop the Maxigro you will drop your micros too low, keeping it the same keeps N too high, and making up for it with Koolbloom which is literally two things P/K your not gunna be making up for it.....and the problems arise. Give her a shot though.

 

[LexLuthor]

@Dirty White Boy- You got some good points, when I flower them I plan on keeping N around 80-100 ppm which I don't think will cause problems with my micros because of the tap water I use, but I'll find out when the time comes. If it doesn't work good then I'll just grab a $15 bag of MaxiBloom :) or use the rest of my Tiger Bloom, but I'll still use MaxiGro during veg.

@Lex- Have you used the Jack's? Seems much cheaper then the MB.

I never used Jack's, but I've done research on it and I thought about going that route. It is less expensive then all the major "cannabis" ferts, but I needed something right away and since I was at the hydro store to buy new soil I just picked up the MaxiGro because I didn't have time to order Jack's online and wait for it in the mail. I'm also growing in soil right now and I think most of there products are made for hydro, but either way I'll probably end up using Jack's after I use all of my current fert stock. The good thing about GH Maxi series is that its a powder fert and is less expensive then all of the popular liquid ferts I've seen. Also, I heard and seen from alot of people that Jack's works great.
